AWS Cloud Operations & Migrations Blog

The latest from AWS Organizations (Fall 2021)

AWS Organizations provides features that customers can utilize to manage their AWS environment across accounts. When paired with other AWS services, AWS Organizations helps you manage permissions, create and share resources, govern your environment, and centrally control your security requirements. Here’s what our team has been up to since Spring 2021.

Programmatically manage alternate contacts for member accounts

Ensure that the right contacts receive important notifications for member accounts in your organization. Now you can programmatically update billing, operations, and security contacts for accounts in your organization. Managing alternate contacts is essential as your organization scales to hundreds or thousands of accounts, thereby saving you time and reducing the operational burden.

Furthermore, you can designate a member account to manage this on behalf of the organization with delegated administration. For more information, and an example of applying changes across your organization, refer to the following blog: “Programmatically update alternate contacts on member accounts using AWS Organizations“.

Generate custom IAM policies by using AWS CloudTrail data from member accounts

AWS Identity and Access (IAM) Access Analyzer helps you identify resources that may inadvertently allow access from outside the organization. You can also create custom IAM policies by utilizing Access Analyzer. It can identify access usage patterns from AWS CloudTrail in your organization, and then assist you with creating policies with only the required permissions. This helps you achieve least-privilege access in order to secure your environment. Learn more about this feature by reviewing the What’s New post.

Tag policy increases limits for policy size and applied tag policies

Tag policies let you programmatically define acceptable tags for your AWS resources, thereby letting you ensure that consistent tags are applied when resources are created across your organization. The tag policy size limit is now 10k characters (4x larger than the previous limit of 2.5k). You can also apply up to 10 tag policies at each organization level (root, each OU level, and member accounts). Learn more about this feature by reviewing the What’s New post.

If you want to enforce tags upon resource creation, apply this Service Control Policy (SCP) that limits tag-less resource creation. Utilizing an SCP to require a tag and a tag policy to define allowable tags on a resource are best practices for enforcing tags across your organization.

Share S3 on Outposts to multiple accounts

Amazon S3 on Outposts makes it easier to store, secure, tag, and control access to the data on your AWS Outposts. This allows you to extend AWS infrastructure, services, and tools to virtually any data center, co-location space, or on-premises facility. Now Amazon S3 on Outposts supports sharing S3 capacity across multiple accounts within an organization by using AWS Resource Access Manager (RAM). This provides flexibility so that multiple teams within your organization can create and manage buckets, access points, and endpoints for S3 on Outposts. To learn more, visit the S3 on Outposts page.

Aggregate and customize organization health alerts

Finally, quickly diagnose and resolve issues impacting applications and workloads by using AWS Health Aware. Utilize AWS Health Aware to get aggregated account level alerts from across your organization, and configure these alerts in order to notify teams on channels such as Slack, Microsoft Teams, or email. Learn more about this feature by reading the blog, Customize AWS Health Alerts for organization and personal AWS accounts.
